All's fine.

Well this is what I did:
11 [15:53:38] root@theirongiant:/usr/src/linux/drivers/i2c>> grep 'define DEBUG' . -r
./i2c-core.c:#define DEBUG 1 /* needed to pick up the dev_dbg() calls */
./scx200_acb.c:#define DEBUG 0
./i2c-sensor.c:#define DEBUG 1
./i2c-algo-bit.c:/* #define DEBUG 1 */
./i2c-dev.c:#define DEBUG 1
./i2c-algo-pcf.c:/* #define DEBUG 1 */ /* to pick up dev_dbg calls */
./busses/i2c-amd756.c:/* #define DEBUG 1 */
./busses/i2c-ali15x3.c:/* #define DEBUG 1 */
./busses/i2c-i801.c:/* #define DEBUG 1 */
./busses/i2c-piix4.c:#define DEBUG 1
./busses/i2c-sis96x.c:/* #define DEBUG */
./busses/i2c-ali1535.c:/* #define DEBUG 1 */
./chips/adm1021.c:#define DEBUG 1
./chips/lm75.c:/* #define DEBUG 1 */
Did I do the right thing?

Unfortunately I didn't get anything special:
serio: i8042 KBD port at 0x60,0x64 irq 1
i2c /dev entries driver module version 2.7.0 (20021208)
i2c-piix4 version 2.7.0 (20021208)
piix4-smbus 0000:00:07.3: Found Intel Corp. 82371AB/EB/MB PIIX4 device
registering 0-004d
Advanced Linux Sound Architecture Driver Version 0.9.4 (Mon Jun 09 12:01:18 2003 UTC).
PCI: Enabling device 0000:00:0c.0 (0000 -> 0003)
I let it boot, thinking I might try using it but I must've pressed
ctrl-alt-del because when I woke up an hour later (ahm - it got REALLY
boring watching the laptop boot :) it was midway through a reboot. What's
more is that I believe the problem survived the reboot because my default
kernel the hasn't any i2c code in it got as far as:
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
PIIX4: IDE controller at PCI slot 0000:00:07.1
PIIX4: chipset revision 1
PIIX4: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0x1040-0x1047, BIOS settings: hda:DMA, hdb:pio
ide1: BM-DMA at 0x1048-0x104f, BIOS settings: hdc:DMA, hdd:pio
hda: IC25N020ATCS04-0, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hdc: DV-28E, ATAPI CD/DVD-ROM drive
ide1 at 0x170-0x177,0x376 on irq 15
By the time I woke up and it was't getting anywhere fast. I got impatient
then though and just power-cycled my laptop and all was well.
Anything else I can do? I've got a null-modem cable now so I can do
anything where that might come in handy.
